Pronounced "pipe". In a UNIX shell, it is used to redirect the standard output (stdout) of a command to the standard input (stdin) of the next.

ALso, in C, C++ and others, it is the symbol for the logical expression 'or'.

^^^ outputs all entries in current directory that have the letter 'e'. Takes output of 'ls' and supplies that as the pattern grep looks for.

Used for adding the most physiologically extreme emphasis to a sentence. It is many times more intense than an exclamation point. By adding this at the end of a sentence you are implying that you are exclaiming so intensely that you have destroyed your vocal chords. Two or more of these at the end of a sentence is unnecessary as that would mean you have destroyed two or more sets of vocal chords which is not possible.

This is the ultimate form of "ok" (in the disdainful sense), where the letter "k" doesn't even suffice how much you don't give two damns. "|" is simply the letter K but without the two strokes (chevron?) on the right.

Used only when 'k' doesn't help cut it.
Example:

Some random e-girl on kik: Hey handsome, wanna see videos of me while I play with myself?
Me: No
E-girl: But it's only $60, and if you could reeeeally spoil me some more, I'll even throw in some close up pics😘😜😋
Me: |

Expanding brain meme example:

Okay - No brain activity
Ok - Mild brain activity
K - Huge brain activity
| - Brain literally transcends into a higher level of consciousness
